Rear fender delete kit Vader 125

[Goody302]

Hi guys, new here, have read quite a bit of good info here, helped me in assembly yesterday of my Vader.
Anyways, will a Grom rear fender delete kit work on a vader? Maybe there is another way to do it as well. Any tips, or kit that works that you guys could point me in the direction to would be great.

Also, when installing a 17t sprocket, will I need to lengthen chain? Or is there enough adjustability with rear tire to compensate?
Thanks!
